The RKS1J270MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It provides 27 µF capacitance at a 63 V rating in a compact φ10 × 10 mm can-style SMD package.

Engineered for general-purpose electronics that require low equivalent series resistance and robust ripple handling, this part delivers high-frequency ripple current capability, low loss (tanδ), and extended high-temperature endurance for reliable operation up to 125°C.

Key Features

• Capacitance & Tolerance — 27 µF nominal with tolerance of −20% to +20% at 20°C, 120 Hz.
• Voltage Rating — Rated for 63 V DC operation.
• Low Loss / Stability — Tangent of loss angle (tanδ) of 0.12 measured at 20°C, 120 Hz, supporting low dissipation in AC environments.
• Low ESR — Equivalent series resistance specified as 30 mΩ at 20°C, 100 kHz, enabling efficient high-frequency performance.
• High Ripple Current Capability — Low-frequency ripple current of 140 mA at 120 Hz and high-frequency ripple current of 1.4 A at 300 kHz for demanding power applications.
• Leakage Current — Leakage not exceeding 100 µA after standard conditioning.
• High Temperature Endurance — Load life of 3000 hours at 125°C under rated voltage for extended durability in hot environments.
• Package & Mounting — Surface-mount, radial can SMD package φ10 × 10 mm with embossed carrier taping and moisture-proof packing for assembly readiness.
• Compliance & Assembly — RoHS compliant; reflow soldering compatibility up to 260°C peak (measurement at capacitor top) per RKS series soldering guidelines.

Typical Applications

• Power conversion and DC–DC outputs — Low ESR (30 mΩ) and 1.4 A high-frequency ripple capability make this capacitor suitable for output filtering and energy smoothing in converter stages.
• High-frequency decoupling — Low loss (tanδ 0.12) and high ripple current support stable decoupling at switching frequencies common in power electronics.
• Industrial electronics — Rated to operate from −55°C to 125°C with a 3000-hour life at 125°C, fitting rugged industrial temperature and endurance requirements.
• General-purpose electronic assemblies — The SMD φ10×10 can package and embossed carrier tape packaging ease automated placement for a wide range of board-level applications.

Unique Advantages

• High ripple tolerance: 1.4 A at high frequency and 140 mA at low frequency provide margin for demanding switching environments.
• Low ESR for efficient performance: 30 mΩ at 100 kHz reduces resistive losses and heat generation in high-current paths.
• Extended high-temperature life: 3000-hour endurance at 125°C helps ensure long-term reliability in elevated-temperature applications.
• Compact SMD can form factor: φ10 × 10 mm radial can-style SMD fits dense board layouts while supporting automated placement and moisture-proof taped packing.
• Stable electrical characteristics: Specified tanδ and leakage limits support predictable behavior across frequency and temperature ranges.
• RoHS compliant: Meets environmental compliance requirements for modern assemblies.
